patch 8.2.4193: cannot use an import in 'charconvert' Commit: https://github.com/vim/vim/commit/f4e88f2152c5975a6f4cfa7ccd745575fe4d1c78 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jan 23 14:17:28 2022 +0000 patch 8.2.4193: cannot use an import in 'charconvert' Problem: Cannot use an import in 'charconvert'. Solution: Set the script context when evaluating 'charconvert'. Also expand script-local functions in 'charconvert'.

" Settings for test script execution
" Always use "sh", don't use the value of "$SHELL".
set shell=sh

" Only when the +eval feature is present. 
if 1
  " While some tests overwrite $HOME to prevent them from polluting user files,
  " we need to remember the original value so that we can tell external systems
  " where to ask about their own user settings.
  let g:tester_HOME = $HOME
endif
